A new CDC study reports that virtually all cases of the common influenza strain, H1N1 are resistant to Tamiflu, the main drug used to treat it. The research report and an editorial were released online by the Journal of the American Medical Association. http://jama.ama-assn.org/cgi/content/full/2009.297

According to the research, more than 98% of H1N1 cases tested by the CDC were resistant to the drug. The accompanying editorial calls into question the value of stockpiling drugs for a pandemic if they won’t work.

In other flu news, The Washington Post reports that two Maryland teens, ages 13 and 15, have died as a result of the flu.. Although it was not clear whether the two boys had received flu shots, it appears both were healthy young adults.


The Post also notes that an increasing number of cases are coupled with bacterial infections, such as MRSA. Symptoms of these infections are hard to distinguish from flu symptoms. By the time the bacterial infection is recognized, it is often too late for antibiotics.
